| Grasshopper
Warbler |
| Main arrival is in
usually in mid-April and has become much commoner than
previously here. This may be due to an increase in
available habitat. There are two September records of
genuine migrants, but the origin of the majority of
Autumn records, is believed from birds which have bred in
the area during the Summer. |
